Resurgence following removal of alternative reinforcement has been studied in non-human animals, children with developmental disabilities, and typically functioning adults. Adult human laboratory studies have included responses without a controlled history of reinforcement, included only two response options, or involved extensive training. Arbitrary responses allow for control over history of reinforcement. Including an inactive response never associated with reinforcement allows the conclusion that resurgence exceeds extinction-induced variability. Although procedures with extensive training produce reliable resurgence, a brief procedure with the same experimental control would allow more efficient examination of resurgence in adult humans. We tested the acceptability of a brief, single-session, three-alternative forced-choice procedure as a model of resurgence in undergraduates. Selecting a shape was the target response (reinforced in Phase I), selecting another shape was the alternative response (reinforced in Phase II), and selecting a third shape was never reinforced. Despite manipulating number of trials and probability of reinforcement, resurgence of the target response did not consistently exceed increases in the inactive response. Our findings reiterate the importance of an inactive control response and call for reexamination of resurgence studies using only two response options. We discuss potential approaches to generate an acceptable, brief human laboratory resurgence procedure.
在非人类动物、发育障碍儿童和正常成年人中,已经对去除替代强化物后的行为复发进行了研究。针对成年人的实验室研究包括没有受控强化历史的反应、仅包括两种反应选项,或者涉及广泛的训练。任意反应能够控制强化历史。纳入一个从未与强化相关联的非活性反应,可以得出行为复发超过消退诱导变异性的结论。虽然经过广泛训练的程序会产生可靠的行为复发,但具有相同实验控制的简短程序将能更有效地检验成年人的行为复发情况。我们测试了一种简短的、单节次的三选项强迫选择程序作为大学生行为复发模型的可接受性。选择一种形状是目标反应(在第一阶段得到强化),选择另一种形状是替代反应(在第二阶段得到强化),而选择第三种形状从未得到强化。尽管对试验次数和强化概率进行了操纵,但目标反应的行为复发并没有始终超过非活性反应的增加。我们的研究结果重申了非活性对照反应的重要性,并呼吁重新审视仅使用两种反应选项的行为复发研究。我们讨论了生成可接受的简短人类实验室行为复发程序的潜在方法。
